Résumé
Objective To establish an HPLC method for the simultaneous determination of 10 components in the active parts of Uygur medicine Dracocephalum Moldavica L.Methods The determination was performed on a Shim-pack ODS(4.6 mm×250 mm,5 um)column with the mobile phase consisting of acetonitrile(A)-0.5%formic acid(B)in aqueous solution in a gradient elution mode(0-30 min,17%A;30-60 min,17%→ 28%A;60-78 min,28%A)at a flow rate of 1.0 mL·min-1.The temperature of the chromatographic column was 35℃and the detection was monitored by a UV detector at 330 nm.Results Cof-feic acid,p-coumalic acid,cynaroside,luteolin-7-O-β-D-glucuronide,apigenin 7-O-glucuronide,rosmarinic acid,diosmetin7-O-β-D-glucuronide,salvianolic acid A,tilianin,apigenin were well separated under this chromatographic condition,and the linear relation-ship were good in the concentration range examined(r＞0.999 2).The overall recoveries ranged from 91.83%to 106.43%with the RSD ranging from 0.38%to 2.22%.Conclusion The established content determination method is highly accurate and reproduci-ble,and suitable for the analysis and quality control of the active parts of Dracocephalum Moldavica L.
Résumé
OBJECTIVE To establish the method for t he content determination of 5 active components in Yixin badiran jibuya granules and their fingerprints. METHODS High performance liquid chromatography method was adopted to determine the contents of luteolin- 7-O-β-D-glucuronide（LG），apigenin-7-O-glucuronide（APG），rosmarinic acid （RA），diosmetin-7-O-β-D-glucuronide （DG）and tilianin （TL）in 10 batches（No. S 1-S10）of Yixin badiran jibuya granules. The fingerprints of 10 batches of Yixin badiran jibuya granules were drawn by Similarity Evaluation System of Chromatographic Fingerprint of Traditional Chinese Medicine（2004 A edition ），and similarity evaluation and cluster analysis were also performed. RESULTS The contents of LG ， APG，RA，DG and TL in 10 batches of Yixin badiran jibuya granules were 0.279 5-0.449 9，0.082 4-0.135 3，0.184 8-0.472 1， 0.149 0-0.332 6，0.311 2-0.623 3 mg/g，respectively. A total of 13 common peaks were demarcated in the fingerprints and were identified as LG （peak 2）APG（peak 6），RA（peak 7），DG（peak 8），TL（peak 11）. The similarity ranged from 0.598 to 0.990. The results of cluster analysis showed that S 6-S10 were clustered into one category and S 1-S5 were clustered into one category. CONCLUSIONS Established method for content determination and fingerprints can be used for the quality control for Yixin badiran jibuya granules.
